副驾驶事件

2026年8月3日，UTC时间06:52至11:25期间，部分GitHub Copilot用户在使用聊天和代理功能时遇到错误。列出可用模型的请求失败，由于每次聊天或代理交互都始于获取模型列表，受影响用户的请求因此失败。事件期间，平均约有3%的模型列表请求失败（约97%成功），但在高峰流量时段，失败率显著升高，受影响内部查询的失败率有时接近100%。在单个60分钟窗口内，约有4,066名用户受到影响，主要集中在基于IDE的客户端。底层AI模型本身在整个事件期间保持健康。<br /><br />事件起因是客户端请求模型列表的频率增加，导致内部用户授权查询超出速率限制；速率限制响应以错误形式呈现给用户。我们通过延长Copilot缓存该授权查询的时间来缓解影响，从而减少内部服务的负载，并正在推进额外的容量和速率限制调整。为防止再次发生，我们正在改进对此类故障的监控，调整缓存和速率限制设置，并与客户端团队协调请求模式。

原文On 2026-08-03, between 06:52 and 11:25 UTC, some GitHub Copilot users experienced errors when using chat and agent features. Requests to list the available models failed, and because every chat or agent interaction begins by retrieving the list of models, affected users saw their requests fail. On average about 3% of these model-listing requests failed during the incident (roughly 97% succeeded), but failures were significantly higher during peak-traffic periods, at times approaching 100% for the affected internal lookups. Approximately 4,066 users were affected in a single 60-minute window, concentrated among IDE-based clients. The underlying AI models themselves remained healthy throughout.<br /><br />The incident was caused by an increase in how often clients requested the model list, which pushed an internal user-authorization lookup past a rate limit; the rate-limited responses were surfaced to users as errors. We mitigated the impact by increasing how long Copilot caches that authorization lookup, which reduced load on the internal service, and we have additional capacity and rate-limit changes in progress. To prevent recurrence we are improving monitoring for this class of failure, adjusting cache and rate-limit settings, and coordinating with client teams on request patterns.
